1 claim. (C1. 242-159) This application is a division of application Serial No. 184,504, tiled September 12, 1950, now Patent No. 2,645,434, granted July 14, 1953, which is a division of application Serial No. 107,128, led July 27, 1949, now Patent No. 2,645,554, granted July 14, 1953, which in turn is a continuation-in-part of our application Serial No. 105,428, iiled July 18, 1949, now abandoned.

The present invention relates to a device for use in preparing freshly spun cakes of rayon for aftertreatments and more particularly to an expansible member that can be inserted readily into viscose rayon cakes as a protection during subsequent handling involving liquid aftertreatments and re-winding during the coning operation.

Normally freshly spun cakes of rayon are either subjected to a lacing operation such as shown in U. S. Patent No. 1,988,778, or to a sockingoperation such as that shown in U. S. Patent No. 2,418,657. Both of these systems are more or less complicated and time consuming. The present method employing the device to be hereinafter described is simpler than that of the former patent and more elicient than that of the latter one.

It therefore is an object of this invention to provide a novel type of expansible insert to be employed in the system here involved.

Other objects and advantages of this invention will be apparent from the following detailed description when considered in conjunction with the accompanying drawings, wherein:

Figure 1 is a perspective view of the expansible insert in an uncoiled condition; and

Figure 2 is a perspective view of a cake in which the insert has been inserted and expanded.

Referring to the drawings and more particularly to Figure 1, the numeral indicates a generally rectangular insert made of a suitable liquid permeable material such as preshrunk cotton cloth. Sewed into the top and bottom marginal edges of this insert are llexible metal spring ICC wires 11 and 12 constructed of a high grade stainless steel.

This insert 10 can be introduced into cake 13, either manually or by a simple device that will retain the insert in a coiled state of smaller diameter than the inside of the cake 13 until the insert has been pulled therethrough and expanded around the inside of the cake. The Width of the insert is greater than the height of the cake, so that the tendency of the metallic wires 11 and 12 to return to their uncoiled position Will cause the top and bottom of the insert to be expanded over the top and bottom inside edges of the cake in the manner shown in Figure 2.

ln providing inserts for the freshly spun acid cakes in n the above manner, adequate protection is furnished to the loosely formed convolutions at the inside of the cakes during subsequent liquid pressure treatments, because substantially no washing down of the inner convolutions, particularly at the edges of the cakes, results. Moreover, the inserts furnish protection during the physical handling of the cakes incident to transferring them to different treatment stations.

It is apparent from the above that the yarn can be aftertreated (purified) and re-wound with a minimum of Waste, because the insert substantially eliminates Washing down of the inner edges of the loosely formed convolutions of rayon.

What is claimed is:

In combination with a freshly spun rayon cake for the protection thereof during subsequent treatment and handling, a liquid permeable, generally rectangular cloth having llexible metallic wires attached to its top and bottom marginal flanges, a central portion of said cloth between its top and bottom marginal flanges extending through the interior of the cake, said Wires biasing said central portion to engage the core defining convolutions of the cake and biasing portions of the cloth adjacent to said marginal anges to overlie and engage the respective ends of the cake, the wires extending for more than 360 around the cake and the side edges of the cloth overlapping to form a continuous protective cover.
